I'm using Windows 11. I put the files in the correct folder..
When you download the patch, you're not supposed to move files. Open the RAR file then just move the entire "game" folder and drop it into the directory that already has a folder called "game." If asked to overwrite, press yes.
If you do this correctly, the patch will work. There's 0 reported problems with it. As I mentioned above, just make sure you're using a program like WinRAR or 7zip. Windows' built-in ZIP-extraction does not work.
